In this paper, the improved operation algorithm for parallel 3-phase PWM converter for renewable energy systems is proposed. The proposed algorithm has a higher performance at the light load condition to use 2-phase operation mode on same load conditions with parallel 3-phase PWM converter. To verify the performance of algorithm, theoretical analysis of efficiency is progressed for obtaining the efficient...
In this paper, a hybrid mode control (HMC) is proposed to increase performance of light load operation without an extra hardware for a three phase PWM converter (TPPC). The proposed algorithm changes an operation mode of the TPPC to 3-phase or 2-phase according to the load condition. To select optimal mode change point, performance of TPPC is analyzed. The validity of the proposed algorithm is verified...
